Hello, I'm pretty much new to this site and I could really use some help/advice.

My problem is that one day my 98 240sx base started making a "whoosh" noise when i would press the accelerator; it sounds just like an 18 wheeler/trash truck/large suv (the way it sounds like it sucks a lot of air in). I didn't think too much of it at first because I thought it wasn't my car.
I was wrong, lol.

The noise gets louder as the RPM's go up, and quieter as they go down. I had my brother press the gas a couple of times while I listened to the engine bay and it sounds kinda like it's coming from the radiator fan area.

The sound went away for a couple of weeks. However, it has now returned and everytime I drive/rev my car it makes the noise (I haven't driven it since it started happening). While I was out driving and it was making the noise, I heard a squeak like one of the belts. I investigated further, and if I accelerate hard it squeaks like a b****; it is definitely one of the belts squeaking.

However, I cannot for the life of me 1) figure out how to get the belts off even with the FSM, 2) find any good descriptions (with pictures that is, I found the S13 belt replacement article but it doesn't show the pictures for some reason?? or even red x's??).

I searched this website up and down, google, and 240sx.org. I cannot find any decent information on how to replace these damn belts, lol. Am I missing something??? Can anyone help me out? I really would prefer to learn how to do this myself if possible to save some cash.

Another thing (if this helps/just for general information), I looked where the big white radiator fan meets with the water pump I think it is? or whatever the fan connects to, and I see maybe a piece of a seal, and what appears to be oil all over the fan and the piece that is connected to it.

Could this be causing the noise? Does anyone know off-hand what this is called? (I'm sure I can find out if I search which is no problem, but if someone happened to know quickly I'd appreciate the help greatly!)

Thanks for any and all help.

Bryan
